The rear roll 94 around which theendless heit passes is supported in any suitable manner. it being shownmounted in the upper end of a rock-frame, 9S. aljustable as by means ofrods. 99. pivou l eminecied thereto and adjustable to "liliiiti horizontal positions. aiming device is also pretei in tion will: the es i inthis as a rolli... lii '12 i under side of the in r run m" it it andcarried by rock-armsforming: part of a rockframe, 101, pivoted on a rocks iaft. 102. and adjustable in pos iou r the, purpose of varying the teiu eserter in the be t. The ai'ljustnient device sh wn similar to that at99 in that it en bodi i connected to it. but in addition it has: coiledspr -i-, working between suitaltile stop; and adjustable for the purposeof applying; regulable pressure to the roll 109 and at the same timepermitting yielding of the parts.

The main roll 9 around which the end less belt '2 travels is normallytree, to turn on its shaft 105%. and normally the belt. which is incontact with a considerable portion of the circumference of the mandrel.and the calenderroll 21. by which the belt is held against said mandrel.are free to turn in unison with the paper and the mandrel. These parts.however. are intended at the proper time. as before stated. to be drivenpositively in the reverse direction to that in which the mandrel travelsand for the purpose of obtaining such a movement suitable connectionsare made. preferably LO the main driver. ll e the shaft 6 which carriesthe pinion 9 ior im 'iarting move. mt to the spur-gear 10 that drivesthe mandrel also carries at its inner end a spur-gear, 106. which mesheswith a spur-pinion. 107. near the left-hand end of the shaft 105carrying the roll 93. This pinion 107 is intended to impart movement tothe shaft 105 when a suitable clutch. such as 108. is thrown intoaction. This clutch is intended to be thrown in on the seventh or lastrevolution of the 1 mandrel. and the coupling operation is controlled bya cam. 109, on the cam-shaft. 73, which at the proper point in itsrotation strikes an anti-friction roll carried at the upper end of. ashifting lever. 110. pivoted at 111 on the bed-plate or main frame ofthe machine, which shifting how has a second upwardly-extending arm,112, engaging in the usual manner a collar, 113, shiftable on theleft-hand end of the shaft 105 into engagement with the clutch 108, forthe purpose of starting into rotation the shaft 105 in the samedirection as the mandrel, to cause the belt 92 to travel in a directionopposite that of the surface of said mandrel, and thus produce awiping-0n action or pressure on the paper of the last layer, andespecially at the end of the sheet.

In the machine shown it is intended that the mandrel shall be stopped atthe end of the seventh revolution. Suitable automatic stopping meanswill be employed for this purpose, that shown in the present machineembodying a cam-wheel. 114, on the camshaft 73 near the left-hand endthereof, which eanrwheel cooperates with the starting lever or releasinglever 13 before described. and to restore it to lilSdlOl" mal position.In the construction shown said lever 13 has a second upwardly-extendingarm, which is indicated at 13', terminatin in an antifriction-roll whichdrops into a cam-groove of the cam-wheel 114 when the machine is inreadiness to be stopped. This results in the latching of the lever 13 tothe spring-pressed detent 17 again, as shown in Fig. 9, and theconsequent stopping of the shaft 11. The stopping of, the mandrel.however, does not result in the stopping of the travel of the belt andcalenderroll in the reverse direction to that in which the mandrel wastraveling, and this movement of the endless belt to Wipe on and smoothout the last layer of the tube may continue as long as the operatordeems necessary.

For the purpose of completing the tube by cutting and trimming the same,the usual cutter mechanism may be employed, which comprises acutter-bar, adjustably mounted in the standards 5 and 5, and carryinginthis instance a plurality 115, adapted to be thrown into and out ofaction by a suitable hand-lever, 116, in a well-known manner. a

()n the completion of the winding and cutting of the tube, various partsof the 11' mechanism require to be thrown out of action or operated. Oneelement of the mechanism that will be thrown out of action at this timeis the calender-roll and other elements of'the wiping-on device. The 1throwing of this part of the machine out of action is accomplished inthe present caseby the operator raising a handle and crank, shown at 117and 118, which crank is secured to a shaft, 119, carried by the 1brackets, 120, and having spur-teeth in mesh with the teeth of the racks97. When the crank 118 is thrown up by the operator these spur-pinionswill be turned and thn'mcks. l with the calender-r011 and the upper ofrotary cutters, 1i
